Bo it known that if, lCnv/Aim i. UMGDHILL, (-itizcn of tile i niioclfitntcs, residing at (illiion. in tho county of (mwfoi'il and Matt ofOhio. luii'o invcutcd coitziin new and usolul improvements in Turningill-ovicvs for Motor Vcliicles. of which the following is itSpClilPfiilOfl.

This invcntioo i'olatos -lo an improved iuining lOVlCC for motorvcliiclcs and has as one of its principal. objects to provide a do vicoof this choi'aicioi' wlicrcby su li 2i vcniclc may be icadily turnedaround With-iii ii restricted arcs.

Tlio invention has as a further object to provide :1 dovico wlici'cl'iyone end of the veliiclo may simply he swung in. on RH? for turning thevcniclc around and wherein the motive power of the t'Oi'llQlB may ill?cmplo /od. 'foi' thus swinging tho voliiclc.

And tho invention has ss :1 still im'tlicr obg'cc't lZO pi'ovii'lc adevice which may be readily oii'ipoycil in connection with vs'riousdifffiT-Bl'li; designs of motor vehicles and which may be operatedeasily and quickly.

' position.

in order that the construction, mounting and operation of my improveddevice rosy lis accurately understood 1 have, in tho drawings, shown theinvention in couscotion with :i coi otioiioi typo of motor truck 10. Thesii'. .LI'S of the from: oi the track are indicated Llii ll. thiscomwctiomit may be stated toss the present device is ticulsi'ly"dssignedfor use in connection with motor; ti-mks since it is so often auoccssoi'y incident of heavy hauling, that vehicle must be turned moundbefore unloading. However, ll do not Wish to be limited in this regardsince. as will iippfill as tho descrip tion proceeds, the falf'SiUiZinvention may be used with cqiuilly good re ults in connection withotlici' types of motor voliicles.

in carrying the im'c'ntion into cficct, I employ 2L yoke 12 pivotallyconnected at its mills in any approved manner to the forward coilso't-tlio side bars 11 of the truck frame. ilipi-oding from this yokemedially thereof {1TB fork arms 13 and joiiinalcd between said 60 aimsis a ground Wheel 14% carried by a. stub shaft 15'. iiivcted 0?otherwise secured at its curls to the side bars ll of the truck frame intlic roar of the yoke 1:2 is a bracket 16 and cktcodiog forwardly fromthis bracket me- 615 dislly tliciool om spaced cars 17. ?ivoted hotwcenthose cars on. as particularly shown in ii i gui'o 3, coziapiiiiionclamping 'iiws 18 ioi'mod their oui-cr cod portions to'engage and litsi'ound the innermost of the 7s fork aims 155 of the yoke Hid extendingfreely through said jaws is a bolt 19. Emuwounding the cod poctions" ofthis liolt are sprin tgs 90 holding the jaws shutting. N01 molly. theground wheel H is. as shown iii ?5 dot .51 lines Figure l of thedrawings, carried in inoctivc position at the front of the truck and toso dispose this wheel it is. simply necessary to swing the yoke 12 11vsrdly until the Wheel lies in front of too so engine radiator of thetruck. For securing the wheel in inactive position I provide a catch 21which is suitably connected to the filler tube of tiic radiator and. isdisposed to engage over the periphery of the Wheel when as ills yoke 12-is swung upwardly. This catch .Will, as will be seen, prevent themovement =01 the wheel against the radiator and W111 zilso preventoccidental. downward swingiiig of the Wheel. 9o

Attention now (liTQCt-ECi to tilfi fact that the ground Wheel 14.- is,as shown in tiis drawings, adapted to support the front Wheels of timetruck clear oi the ground. Thus, when the ground wheel is swung Q5downwardly from its inactive position, said wfocsl will engage theground some distance in advance of the. front wheels ol the truck,

tho yoke 12 then inclining forwardly from the iiont of the side inns 1.1of the mo truck ii'omo. Consequently. by then di'iving til-c truckforwardly, the yoke will be moved. to its active 'vorticsl position forelevating the fiont Wliccls of the truck clear of the ground when theclamping jaws 18 10;?- will engage the innermost of the fork arms 13 ofthe yoko in! securingthe yoke in such position. As will loo clear.rotation of the groundwvhcsl will tlicn sorve to swing the torward endof the vehicle in an org fol-11G turning the vehicle around and thepresent invention coiiteinpistes that the motive power oil the vehicleshell he employed for this purpose Any upproved mechanism may he usedforectively coupling she engine to the ground wheel but in she drewing.1 have shown the provisioncf a flexible shaft 2:2 suitably coupled atone end with she engine end equipped st ,ilcs opposite end withuniversalv joint which carries a sleeve 23 ei'igageeble over the innerend of the stub shaft 15, this shaft being squared at its inner end tocoect with said sleeve. Thus, the ground wheel may be readily rotatedfor lurning the truck around while the sleeve 23 may be quicklydctechedfrom she stub shaft 15 so that the ground wheel may be swungupwardly to its inactive position. After the truck has been iurnedaround as just indicated, the jaws 18 may be released from the yoke 13,when by driving the truck beclrwairdly a slight distance, the frontwheels of the truck will be again lowered into engagement with theground. This done, the yolie 12 may be manually swung upwardly l oengage the ground wheel lei with the catch ingly be seen that I providee particularly simple end. effective construction for the purpose so;forth and a device which may be readily employed in connection with.substantially any conventionel design of motor vehicle.

Having thus described the invcueion, whom is claimed as new is:

l. The combineicion with e motor vehicle, of a yoke pivoteliy connectedto she vehicle to swing in a direction, longitudinally thereof, :1ground wheel carried by said yoke, the
